16 Claims. (Cl. 18S-36) This invention relates to frames foriirescreens, license plates, mirrors and other articles of the typecomprising longitudinal and transverse members interconnected to form arectangular frame with slots in their opposing faces to receive therescreen or other article to be mounted therein. v

Objects of the invention are to provide a frame which is rigid anddurable in construction, which can be readily assembled anddisassembled, `which is neat and attractive in appearance, and generallyto improve frames of the type to which the present invention relates. i

Other objects of the invention will be evident from the followingdescription and accompanying illustration of typical `embodiments of theinvention in which `Fig. 1 is an elevation of a two-section ilrescreen;

Fig. 2 is a similar View, parts being shown in section and parts brokenaway;

Figs. 3 and 4 are detail sectional viewsof modifications;

Fig. 5 is a section on line 5-'5 of Fig. 3;

Fig. 6 is a section on line 6-6 of Fig. 4;

Fig. 'I is an inside face view of the longitudinal frame member of Figs.3 and 5;

Fig. 8 is a similar view of the longitudinal'member of Figs. 1 and 2;

A Fig. 9 is a detailed sectional view of still another modiication; and

Fig. 10 is an end view of the modification of Fig. 9.

The particular embodiment of the invention shown in Figs. 1, 2 and 8comprises longitudinal frame members I, transverse frame members 2,screen sections 3, hinge straps 4 and a tie rod 5. The longitudinalmembers I have slots 6 in their inner faces, these slots terminatingshort of the ends of the members and having enlargements 'I at theirextremities. The transverse frame members 2 have slots I 0 extendingthroughout their vfull lengths on their inner faces. The screen sections3 comprise longitudinally and transverse rods 8 and 9 integrally joinedtogether at the corners with the wire mesh of the screens mounted overthese rods. The longitudinal rods 8 have extensions II and I2 at theirupper and lower ends extending through openings I3 in the ends of thetransverse frame members 2. Threaded on'the ends of the projectingportions II and I2 are nuts I4 and I5. The nuts I4 have tapered portionsI6 telescoping inside the tubes I- to center the nuts in the tubes; andthe nuts I5-have 4cylindrical portions similarly telescoping into thetubes. At the lower and upper ends' of the two central longitudinalframe members the nuts I'I telescope entirely inside the tubes with therods 8 extending therethrough to serve as pintles for the hinge pieces4. The two hinge 5 pieces are tied together by the rod 5 which threadsinto the lower hinge member and receives a nut I 8 at its upper end.

To assemble the parts 'of the embodiment shown in Figs. i, 2 and 8 thetransverse frame members 10 2 are rst fitted over the top and bottom ofthe screeen sections with the projecting portions II and I2 of the rods8-y projecting through the openings I3 in the ends of the transverseframe members. The longitudinal frame members I 15 are then tted overthe sides of the screen sections with the ends of the transverse member2 fitting into the enlarged ends 'I of the slot B in the 'inner faCes ofthe longitudinal frame members. In the case of the upper outer cor- 20ners of the frame, where the portions II project a considerableVdistance above the upper transverse members 2 the longitudinal framemembers I may rst be hooked over the projecting portions I I, with thelower ends of these frame 25 members extending outwardly at an angle,the members then being simultaneously moved downwardly and swunginwardly until they reach the position shown in Figs. l and 2. Near theend of this swinging movement the screen is lifted 30 until the crossrods 9 touch the top of the inner peripheries of thetransverse tubes 2thereby to permit the lower end of the slot 6 to pass under the lowerend of rod 8.

The modication shown in Figs. 3 and 5 dif- 35 fers y'from that shown inFigs. 1, 2 and 8 in that the longitudinal frame member I has a slotextending throughout its full length as shown at 6. in Fig. '7 and inthat the nut I4 is replaced by a nut I4 which has an annular groove tore- 40 ceive the end of the frame member I', with a peripheral ange 20which covers the upper end of the slot 6. Whereas the nut I4 seats onthe end of the longitudinal frame member with clearance between the nutand the end of the trans- 45 verse frame member 2, the nut I4 seats onthe end of the transverse frame member 2 with cleary ance between theend of the longitudinal frame member I and thebottom of the annulargroove in the nut. 50

The modification shown in Figs. 4 and 6 comprises rectangular framemembers ZI and 22 instead of circular frame members as in the precedinggures. With this type of construction a ller piece 23 is preferablyfitted. into the ends of 55 the longitudinal frame member 2| underneaththe nut 24. The filler piece 23 preferably has the same polygonal crosssection as that of the longitudinal frame member 2|.

In the modification shown in Figs. 9 and 10 the polygonal filler 23' isrecessed to receive the nut 24 so that the nut does not project.

It should be understood that the present disclosure is for the purposeof illustration only and that this invention includes all modicationsand equivalents which fall within the scope of the appended claims.
